General Information
Despite being relatively long by indie visual novel standards (about 80,000 words), The Devil's Whisper has a full, professional voice cast to bring each of the characters to life. They might not have the big-name impact of a Troy Baker or Laura Bailey, of course, but the performances are admirable, and if you imagine this as being like the B-horror films, there's every chance that some of these voice talents might follow the path of a Jamie Lee Curtis or Kevin Bacon and go from humble horror victim to major star down the track.
It's just as well the voice acting pulls the heavy lifting to give these characters personality, because they're not much to look at. It is great that the character art is not AI-generated and it's always good to see developers giving journeyman artists commissions – God knows there's enough of them on Reddit, DeviantArt and others trying to get their big break. Projects like The Devil's Whisper help the artist refine their craft, get some credits going and build from there. Some people will enjoy how The Devil's Whisper looks, I am quite certain of that. It's simply not my taste in aesthetics.
For the most part, it's written well enough, too, despite being an enormously difficult genre to work in. With horror there only needs to be one line of dialogue out of place or one character motivation inconsistent for the delicate suspension of disbelief to be shattered. In video games it's even more difficult because the writer can never quite be sure what the player is doing or the decisions they've made, so every thread needs to be carefully balanced. The Devil's Whisper isn't perfect in this regard, but it is written with clear intent by an author that clearly cared about what they were writing.
The number of paths through the narrative is also very impressive. The Devil's Whisper frequently offers players choices about how to have the characters react, and "that decision will have consequences" pops up ominously when those decisions are made. Characters live and die based on these choices, and because you do get a chance to experience the perspective of each character those deaths can be a surprisingly high impact.
